Check Digit Verification of cas no

The CAS Registry Mumber 143809-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143809-90:
(8*1)+(7*4)+(6*3)+(5*8)+(4*0)+(3*9)+(2*9)+(1*0)=139
139 % 10 = 9
So 143809-90-9 is a valid CAS Registry Number.
